Building Apps with Location & Maps. Connecting to the Network. In order to perform network operations in your application, your manifest must include the following permissions: Design Secure Network Communication Before you add networking functionality to your app, you need to ensure that data and information within your app stays safe when transmitting it over a network.
To do so, follow these networking security best practices: Minimize the amount of sensitive or personal user data that you transmit over the network. Send all network traffic from your app over SSL. For more information on applying secure networking principles, see Android's networking security tips. Choose an HTTP Client Most network-connected Android apps use HTTP to send and receive data. Introducing Network Operations on a Separate Thread To avoid creating an unresponsive UI, don't perform network operations on the UI thread. The following Activity snippet uses a headless Fragment to encapsulate asynchronous network operations. Private void startDownload() { if (! HttpURLConnection. Public abstract class HttpURLConnection extends URLConnection A URLConnection with support for HTTP-specific features.
See the spec for details. Uses of this class follow a pattern: For example, to retrieve the webpage at URL url = new URL(" HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); try { InputStream in = new BufferedInputStream(urlConnection.getInputStream()); readStream(in); } finally { urlConnection.disconnect(); } Secure Communication with HTTPS Response Handling HttpURLConnection will follow up to five HTTP redirects. Posting Content For example, to perform an upload: HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); try { urlConnection.setDoOutput(true); urlConnection.setChunkedStreamingMode(0);
Android Network Connection. Android lets your application connect to the internet or any other local network and allows you to perform network operations.
A device can have various types of network connections. This chapter focuses on using either a Wi-Fi or a mobile network connection. Checking Network Connection Before you perform any network operations, you must first check that are you connected to that network or internet e.t.c. For this android provides ConnectivityManager class. ConnectivityManager check = (ConnectivityManager) this.context.getSystemService(Context.CONNECTIVITY_SERVICE); Once you instantiate the object of ConnectivityManager class, you can use getAllNetworkInfo method to get the information of all the networks. NetworkInfo[] info = check.getAllNetworkInfo(); Accurance 3D. Visitor counter project using Arduino - Gadgetronicx. Vehicle Tracking System Project using GPS and Arduino. In our previous article, we have learned about “How to interface GPS module with Computer and How to make a GPS updated Clock”.
In this project we are going one step ahead with GPS and going to track a vehicle using GPS and GSM. This Vehicle Tracking System can also be used for Accident Detection Alert System, Soldier Tracking System and many more, by just making few changes in hardware and software. Tracking of vehicle is a process in which we track the vehicle location in form of Latitude and Longitude (GPS coordinates). GPS Coordinates are the value of a location.
This system is very efficient for outdoor application purpose. This kind of Vehicle Tracking System Project is widely in tracking Cabs/Taxis, stolen vehicles, school/colleges buses etc. Components Required: ArduinoGSM ModuleGPS Module16x2 LCDPower SupplyConnecting Wires10 K POT GPS Module and Its Working: We can extract coordinate from $GPGGA string by counting the commas in the string. Circuit Explanation: Working Explanation: GpsGate - GpsGate Server. GpsGate Server is a leading web based GPS tracking platform successfully used by transportation companies, police and fire departments, utility companies, service organizations and other businesses with mobile workers around the world.
You can install GpsGate Server on-site on your own server or subscribe to it as a hosted service. Features The GpsGate Server platform supports localization, re-branding, application extension and integration with other systems through open APIs. Tracking partners can offer GPS tracking services under their own brand. Multiple map providers are supported, as well as custom map import. A lightweight web interface is available for mobile devices so that you can access GpsGate Server from any location. Pre-configured application templates are included with the GpsGate Server platform to get you started quickly. Feature list Device support Supported tracking devices.
